AI-Powered RAG Pipeline for Enterprise Documentation

AI/ML Platform
Client: Internal Project
Period: 2024 - Present

An enterprise-grade RAG system that allows organizations to query their internal documentation using natural language. The system uses vector embeddings, semantic search, and LLM integration to provide accurate, context-aware answers from company knowledge bases. It supports multiple document types, maintains conversation context, and provides source citations for transparency. The system is optimized for latency and cost while maintaining high accuracy.

Problem Statement

Employees spent significant time searching through documentation to find answers. Traditional keyword search was insufficient for complex queries.

Architecture & Technical Approach

Document ingestion pipeline processes and chunks documents, generating embeddings stored in Azure Cognitive Search. Query pipeline retrieves relevant chunks, assembles context, and sends to LLM for generation. Redis caching reduces latency and costs.

Challenge

Optimizing latency and cost for production use while maintaining high accuracy and handling large document collections

Solution

Implemented caching, prompt optimization, selective retrieval strategies, and hybrid search combining vector and keyword search

Impact

Reduced support ticket volume by 40%, improved employee productivity, and enabled self-service information access

Key Features

Vector search with Azure Cognitive Search
Multi-document chunking and embedding
Context-aware LLM responses
Hybrid search (vector + keyword)
Token usage optimization
Secure access control and audit logging
Conversation history and context management
Source citation and transparency
